[0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device / storage medium / apparatus for determining a threshold in non-contention random access (CFRA). Background Art

[0002] In a wireless network system, a UE (User Equipment) generally needs to perform a CFRA (Contention-Free Random Access) process based on an RSRP (Reference Signal Received Power) threshold.

[0003] In the related art, when the UE triggers CFRA, if the RSRP threshold is configured in the CFRA configuration, the CFRA process will be performed based on the RSRP threshold in the CFRA configuration; if the RSRP threshold is not configured in the CFRA configuration, the CFRA process can be performed based on the RSRP threshold in the CBRA (Contention-based Random Access) configuration.

[0004] However, when the UE performs the CFRA process based on the RSRP threshold in the CBRA configuration, if the UE corresponds to multiple CBRA configurations, the UE cannot determine which CBRA configuration's RSRP threshold is specifically selected to perform the CFRA process.

[0047] The following describes in detail the threshold determination method, apparatus, user equipment, network-side equipment, and storage medium in CFRA provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0048] Figure 1 A flow chart of a method for determining a threshold value in a CFRA according to an embodiment of the present disclosure is provided. The method is executed by a UE. Figure 1 As shown, the threshold determination method in the CFRA may include the following steps:

[0049] Step 101: Acquire a CBRA configuration sent by a network-side device, where the CBRA configuration includes at least one of a first version of a CBRA configuration and a second version of a CBRA configuration, where the first version is earlier than the second version.

[0050] In one embodiment of the present disclosure, the UE may refer to a device that provides voice and / or data connectivity to a user. A terminal device may communicate with one or more core networks via a RAN (Radio Access Network). The UE may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE may be a device on an unmanned aerial vehicle. Alternatively, the UE may be an in-vehicle device, such as a driving computer with wireless communication capabilities, or a wireless terminal connected to an external driving computer. Alternatively, the UE may be a roadside device, such as a streetlight, traffic light, or other roadside device with wireless communication capabilities.

[0051] In one embodiment of the present disclosure, the first version may include at least one version, one of which may correspond to at least one CBRA configuration; the second version may include at least one version, one of which may correspond to at least one CBRA configuration. For example, in one embodiment of the present disclosure, the first version may include Release-15 and / or Release-16, and the second version may include Release-17.

[0052] Furthermore, it should be noted that, in one embodiment of the present disclosure, each CBRA configuration of the second version may correspond to a feature combination, which may include: a combination of one or more features of the Redcap (Reduced Capability) feature, the SDT (Small Data Transmission) feature, the Slice (Network Slicing) feature, and the CE (Coverage Enhancement) feature.

[0053] Furthermore, in one embodiment of the present disclosure, the relationship between the first version of the CBRA configuration and the second version of the CBRA configuration may include at least one of the following:

[0054] The second version of the CBRA configuration is independently configured with the same RSRP threshold as that in the first version of the CBRA configuration;

[0055] The RSRP threshold value in the second version of the CBRA configuration is independently configured differently from the RSRP threshold in the first version of the CBRA configuration;

[0056] The RSRP threshold is not configured in the second version of the CBRA configuration, and the RSRP threshold in the first version of the CBRA configuration is reused.

[0057] In one embodiment of the present disclosure, the RSRP threshold may include at least one of the following:

[0058] SUL (Supplementary Uplink) selection threshold (for example, rsrp-ThresholdSSB-SUL);

[0059] SSB (Synchronization Signal Block) selection threshold (e.g., RSRP-ThresholdSSB and / or msgA-RSRP-ThresholdSSB).

[0060] Furthermore, in one embodiment of the present disclosure, the CBRA configuration may include at least one of the following:

[0061] 2-step CBRA configuration;

[0062] 4-step CBRA configuration.

[0063] Furthermore, in one embodiment of the present disclosure, the UE obtaining the CBRA configuration sent by the network-side device may include: obtaining the CBRA configuration sent by the network-side device via a system message.

[0064] In one embodiment of the present disclosure, the system message may be any system information sent by a network-side device. For example, the system information may be a System Information Block (SIB) x, where x is a positive integer. The SIB x may be an existing system message, a system message that will appear in the future, or a newly defined system message. For example, in one embodiment of the present disclosure, the SIB x may be the existing SIB 1.

[0065] Furthermore, in one embodiment of the present disclosure, the names of the fields carrying the first version of the CBRA configuration and the second version of the CBRA configuration may be the same; and, when the names of the fields carrying the first version of the CBRA configuration and the second version of the CBRA configuration are the same, a suffix needs to be set for the fields carrying the different versions of the CBRA configuration to indicate the version corresponding to the CBRA configuration carried by the field.

[0066] Specifically, in one embodiment of the present disclosure, when the CBRA configuration is a 4-step CBRA configuration, the fields carrying the first version of the CBRA configuration and the second version of the CBRA configuration can be distinguished by different suffixes. For example, in one embodiment of the present disclosure, the field carrying the second version of the CBRA configuration can be: RACH-ConfigCommon-r17.

[0067] Furthermore, in one embodiment of the present disclosure, when the CBRA configuration is a two-step CBRA configuration, the field carrying the second version of the CBRA configuration can be distinguished from the first version of the CBRA configuration by a different suffix. For example, in one embodiment of the present disclosure, the field carrying the second version of the CBRA configuration can be: RACH-ConfigCommonTwoStepRA-r17.

[0068] In another embodiment of the present disclosure, the field carrying the second version of the CBRA configuration can be distinguished from the first version of the CBRA configuration by a different name. For example, in one embodiment of the present disclosure, when the CBRA configuration is a 4-step CBRA configuration, the second version of the CBRA configuration can be carried in a new field. For example, the new field can be: RACH-ConfigCommonExt-r17. In one embodiment of the present disclosure, when the CBRA configuration is a 2-step CBRA configuration, the second version of the CBRA configuration can be carried in a new field. For example, the new field can be: RACH-ConfigCommonTwoStepRAExt-r17.

[0069] Step 102: In response to the UE triggering CFRA, determine whether an RSRP threshold is configured in the CFRA configuration.

[0070] In one embodiment of the present disclosure, the UE triggering CFRA may include at least one of the following:

[0071] Triggering CFRA based on BFR (Beam failure recovery);

[0072] CFRA is triggered based on SI (System Information) request;

[0073] CFRA is triggered based on the switch.

[0074] Step 103: When the RSRP threshold is not configured in the CFRA configuration, determine a target version, where the target version includes the first version and / or the second version, and determine the target RSRP threshold based on the RSRP threshold in the CBRA configuration of the target version.

[0075] In one embodiment of the present disclosure, a method for determining the target version may include at least one of the following:

[0076] Determine the target version based on the network device indication;

[0077] Determine the target version based on the protocol agreement;

[0078] Determine the target version based on UE capabilities;

[0079] The UE autonomously determines the target version.

[0080] In one embodiment of the present disclosure, the method for determining the target version may specifically include at least one of the following:

[0081] Determine the first version as the target version;

[0082] determining the second version as the target version;

[0083] The first version and the second version are determined as target versions.

[0084] Specifically, in one embodiment of the present disclosure, the above-mentioned method of "determining the target version" and the content included in the finally determined "target version" can be arbitrarily combined.

[0085] For example, in one embodiment of the present disclosure, when determining the target version based on the protocol agreement, the first version can be determined as the target version based on the protocol agreement, or the second version can be determined as the target version based on the protocol agreement, or the first version and the second version can be determined as the target versions based on the protocol agreement.

[0086] In another embodiment of the present disclosure, when the UE autonomously determines the target version, the UE may autonomously determine the second version as the target version, or the UE may autonomously determine the first version as the target version, or the UE may autonomously determine the first version and the second version as the target versions.

[0087] In another embodiment of the present disclosure, when the target version is determined based on the network side device indication, the second version can be determined as the target version based on the network side device indication, or the first version can be determined as the target version based on the network side device indication, or the first version and the second version can also be determined as the target versions based on the network side device indication.

[0088] In another embodiment of the present disclosure, when the target version is determined based on UE capabilities, the second version can be determined as the target version based on the UE capabilities, or the first version can be determined as the target version based on the UE capabilities, or the first version and the second version can be determined as the target versions based on the UE capabilities.

[0089] And, in another embodiment of the present disclosure, if there is no network-side device instruction or the UE cannot identify and read the second version of the CBRA configuration based on the UE capability, the first version may be determined as the target version.

[0090] Furthermore, in one embodiment of the present disclosure, there is no mutually exclusive relationship among the above-mentioned "obtaining the target version indicated by the network side device", "determining the target version based on the protocol agreement", "determining the target version based on the UE capability", and "UE autonomously determining the target version", and they can cooperate with each other.

[0091] For example, in one embodiment of the present disclosure, the protocol may stipulate that the UE autonomously determines: the second version is determined as the target version.

[0092] Furthermore, in one embodiment of the present disclosure, after the UE determines the target version, it determines the target RSRP threshold based on the RSRP threshold in the CBRA configuration of the target version. It should be noted that in one embodiment of the present disclosure, when the type of target RSRP threshold is determined to be different, the selected CBRA configuration will also be different. Specifically, when the target RSRP threshold to be determined is the SUL selection threshold, the SUL selection threshold can be determined based on the 4-step CBRA configuration of the target version; when the target RSRP threshold to be determined is the SSB selection threshold of the 2-step CFRA, the SSB selection threshold can be determined based on the 2-step CBRA configuration of the target version; when the target RSRP threshold to be determined is the SSB selection threshold of the 4-step CFRA, the SSB selection threshold can be determined based on the 4-step CBRA configuration of the target version.

[0093] Furthermore, it should be noted that in one embodiment of the present disclosure, the target version may correspond to one or more CBRA configurations, and the method for determining the target RSRP threshold when the target version corresponds to one CBRA configuration is different from the method for determining the target RSRP threshold when the target version corresponds to multiple CBRA configurations. This part will be described in detail in subsequent embodiments.

[0094] In summary, in the threshold determination method in CFRA provided in the embodiment of the present disclosure, the UE will obtain the CBRA configuration sent by the network-side device, and the CBRA configuration includes at least one of the first version of the CBRA configuration and the second version of the CBRA configuration, the first version being earlier than the second version. Then, in response to the UE triggering CFRA, it is determined whether the RSRP threshold is configured in the CFRA configuration, wherein, in response to the RSRP threshold being configured in the CFRA configuration, the target RSRP threshold is determined based on the RSRP threshold in the CFRA configuration, and when the RSRP threshold is not configured in the CFRA configuration, the target version is determined, the target version includes the first version and / or the second version, and the target RSRP threshold is determined based on the RSRP threshold in the CBRA configuration of the target version. It can be seen that an embodiment of the present disclosure provides a threshold determination method for determining a target RSRP threshold for CFRA from a CBRA configuration.

[0095] Figure 2a A flow chart of a method for determining a threshold value in a CFRA according to an embodiment of the present disclosure is provided. The method is executed by a UE. Figure 2a As shown, the threshold determination method in the CFRA may include the following steps:

[0096] Step 201a: Acquire a CBRA configuration sent by a network-side device, where the CBRA configuration includes at least one of a first version of a CBRA configuration and a second version of a CBRA configuration, where the first version is earlier than the second version.

[0097] Step 202a: In response to the UE triggering CFRA, determine whether a reference signal received power (RSRP) threshold is configured in the CFRA configuration.

[0098] For other introductions to steps 201a to 202a, please refer to the above embodiment description, which will not be elaborated here in the embodiment of the present disclosure.

[0099] Step 203a: When the RSRP threshold is not configured in the CFRA configuration, determine a target version, where the target version includes the first version and / or the second version; in response to the target version corresponding to a CBRA configuration, directly determine the RSRP threshold in the CBRA configuration of the target version as the target RSRP threshold.

[0100] In summary, in the threshold determination method in CFRA provided in the embodiment of the present disclosure, the UE will obtain the CBRA configuration sent by the network-side device, and the CBRA configuration includes at least one of the first version of the CBRA configuration and the second version of the CBRA configuration, the first version being earlier than the second version. Then, in response to the UE triggering CFRA, it is determined whether the RSRP threshold is configured in the CFRA configuration, wherein, in response to the RSRP threshold being configured in the CFRA configuration, the target RSRP threshold is determined based on the RSRP threshold in the CFRA configuration, and when the RSRP threshold is not configured in the CFRA configuration, the target version is determined, the target version includes the first version and / or the second version, and the target RSRP threshold is determined based on the RSRP threshold in the CBRA configuration of the target version. It can be seen that an embodiment of the present disclosure provides a threshold determination method for determining a target RSRP threshold for CFRA from a CBRA configuration.

[0101] Figure 2b A flow chart of a method for determining a threshold value in a CFRA according to an embodiment of the present disclosure is provided. The method is executed by a UE. Figure 2b As shown, the threshold determination method in the CFRA may include the following steps:

[0102] Step 201b: Acquire a CBRA configuration sent by a network-side device, where the CBRA configuration includes at least one of a first version of a CBRA configuration and a second version of a CBRA configuration, where the first version is earlier than the second version.

[0103] Step 202b: In response to the UE triggering CFRA, determine whether a reference signal received power (RSRP) threshold is configured in the CFRA configuration.

[0104] Step 203b: When the RSRP threshold is not configured in the CFRA configuration, determine a target version, where the target version includes the first version and / or the second version; and in response to the target version corresponding to at least one CBRA configuration, determine the target RSRP threshold from the RSRP thresholds of the at least one CBRA configuration of the target version.

[0105] In one embodiment of the present disclosure, a method for determining a target RSRP threshold from an RSRP threshold of at least one CBRA configuration of a target version may include at least one of the following:

[0106] Method 1: Determine the target RSRP threshold from the RSRP thresholds of at least one CBRA configuration of the target version based on an instruction from the network-side device.

[0107] Method 2: Determine the target RSRP threshold from the RSRP thresholds configured by at least one CBRA of the target version based on UE capabilities.

[0108] It should be noted that, in one embodiment of the present disclosure, the execution premise of method 2 is that the target version includes the second version. Furthermore, reading of the CBRA configuration of the second version is limited by UE capabilities. Therefore, in one embodiment of the present disclosure, the method for the UE to determine the target RSRP threshold from the RSRP thresholds of at least one CBRA configuration of the target version based on the UE capabilities may include: reading at least one CBRA configuration of the second version based on the UE capabilities, and determining the target RSRP threshold from the RSRP thresholds of the read CBRA configuration.

[0109] It should be noted that in the CBRA configuration of the second version, each CBRA configuration corresponds to a feature combination in the second version, and a UE that does not support a certain feature combination may not be able to identify and read the CBRA configuration corresponding to the feature combination, and thus cannot use the RSRP threshold therein.

[0110] For example, in one embodiment of the present disclosure, assume that the target version includes version 2, which includes CBRA configuration 1, CBRA configuration 2, and CBRA configuration 3. The feature combinations corresponding to CBRA configuration 1, CBRA configuration 2, and CBRA configuration 3 are Redcap, Slice, and CE, respectively. Furthermore, the UE supports Slice. In this case, the target RSRP threshold can be determined from the RSRP threshold of CBRA configuration 2.

[0111] Method 3: Determine the RSRP threshold in the first version of the CBRA configuration as the target RSRP threshold.

[0112] In one embodiment of the present disclosure, the execution premise of the third method is that the target version includes a first version, and the first version corresponds to a CBRA configuration.

[0113] Furthermore, in one embodiment of the present disclosure, when the UE does not receive an instruction from the network-side device, or the UE capability does not support the second version of the CBRA configuration, the third method is used by default, that is, the RSRP threshold in the first version of the CBRA configuration is determined as the target RSRP threshold.

[0114] Method 4: Determine the target RSRP threshold from the RSRP thresholds of at least one CBRA configuration of the target version based on a predefined rule.

[0115] In one embodiment of the present disclosure, the predefined rule may include at least one of the following:

[0116] The maximum RSRP threshold is determined as the target RSRP threshold;

[0117] The minimum RSRP threshold is determined as the target RSRP threshold.

[0118] Method 5: The UE autonomously determines the target RSRP threshold from the RSRP thresholds configured by at least one CBRA of the target version.

[0119] It should be noted that, in an embodiment of the present disclosure, the above methods 1 to 5 can be used individually or in combination to ensure that a unique target RSRP threshold is ultimately determined.

[0120] For example, in one embodiment of the present disclosure, if the UE capability includes only one, and the one UE capability supports a certain feature combination, the CBRA configuration corresponding to the feature combination can be read, thereby determining a unique target RSRP threshold based only on method two, that is, determining a unique target RSRP threshold from the RSRP threshold of at least one CBRA configuration of the target version based on the UE capability.

[0121] In another embodiment of the present disclosure, if the UE capability supports reading multiple CBRA configurations, multiple RSRP thresholds can be determined based on the above-mentioned method 2. On this basis, a unique target RSRP threshold can be further determined from the multiple RSRP thresholds determined based on the UE capability based on method 1, method 4, method 5, or protocol agreement.

[0122] In summary, in the threshold determination method in CFRA provided in the embodiment of the present disclosure, the UE will obtain the CBRA configuration sent by the network-side device, and the CBRA configuration includes at least one of the first version of the CBRA configuration and the second version of the CBRA configuration, the first version being earlier than the second version. Then, in response to the UE triggering CFRA, it is determined whether the RSRP threshold is configured in the CFRA configuration, wherein, in response to the RSRP threshold being configured in the CFRA configuration, the target RSRP threshold is determined based on the RSRP threshold in the CFRA configuration, and when the RSRP threshold is not configured in the CFRA configuration, the target version is determined, the target version includes the first version and / or the second version, and the target RSRP threshold is determined based on the RSRP threshold in the CBRA configuration of the target version. It can be seen that an embodiment of the present disclosure provides a threshold determination method for determining a target RSRP threshold for CFRA from a CBRA configuration.

[0123] Figure 2c A flow chart of a method for determining a threshold value in a CFRA according to an embodiment of the present disclosure is provided. The method is executed by a UE. Figure 2c As shown, the threshold determination method in the CFRA may include the following steps:

[0124] Step 201c: Acquire a CBRA configuration sent by the network-side device, where the CBRA configuration includes at least one of a first version of the CBRA configuration and a second version of the CBRA configuration, where the first version is earlier than the second version.

[0125] Step 202c: In response to the UE triggering CFRA, determine whether a reference signal received power (RSRP) threshold is configured in the CFRA configuration.
